Specification of Letters Patent.

Patented May 21, 1918.

Application filed July 10, 1917. Serial No. 179,764.

To all whom it may concern:

Be it known that I. CHARLES M. ERICKSON, a citizen of the United States, residing at Salt Lake City, in the county of Salt Lake and State of Utah have invented new and useful Improvements in Hammer-Handle Fasteners, of which the following is a specification.

This invention relates to wood working tools, and more especially to split socket fastenings which include a transverse screw to clamp the socket on the handle. While the invention is described herein and illustrated herewith as applied to the socket of a hammer head and such is my preferred use, I do not wish to be limited in this respect as it is quite obvious that the tool head could be otherwise shaped. For instance, it might be a hammer Without a claw, it might be an ax or hatchet. but of necessity it includes a metallic head mounted on a wooden handle by means which forms the subject matter of the present invention-all as hereinafter more fully described and claimed, and as shown in the drawings wherein Figure 1 is a perspective view of a hammer head embodying this invention, showing the same before its application to the handle, and Fig. 2 is a similar view showing the head as clamped on the handle.

ig. 3 is a side elevation and Fig. 4 an end view of a hammer head having a socket with another type of fastening device.

Fi 5 is a side elevation of a head embodying both types of my fastening device and secured upon the handle by both means.

In the drawings I have used the letter H to designate an ordinary handle as of wood, and the letter T to designate the head of the tool which in the present instance is a hammer although, as suggested above, I do not wish to be limited in this respect. The hammer head as herein shown has a driving face D and a claw C, and as usual the slot or opening 0 between the two members of the claw extends nearly to the socket S while the latter is a boss standing at right angles to the head and shaped internally to fit over the outer end of the handle H.

Oomin now to the details of the invention as il ustrated in one type of my invention in Figs. 1 and 2, the socket is split along that side adjacent the claw at 1. which side we might call the inner side as distinguished from the other or outer side which will be adjacent the object struck by the face D in driving. Projecting from the walls of the split inner side are two ears 2 and 3, the former pierced with a threaded opening and the latter with a smooth opening, and through these openings passes a screw 4 whose shank is loose within the smooth opening but threaded into the other open ing as seen where Fig. 1 is broken away and in section. The ear 3 is inset a little over the inner side of the socket. so that the head 5 of the screw when in place may stand out of line with the side wall 6 of said socket. The handle H may or may not be reduced where it passes into the socket, but obviously after it is inserted the screw may be set up to clamp the resilient walls of the socket against it. This form of fastening will. answer for all ordinary uses.

Referring now to the type of my invention shown in Figs. 3 and 4, the socket is formed around its inner end with pliable teeth 7, which, after the insertion of the handle, are bent inward and driven into the Wooden handle in a manner which will be clear.

Referring now to the type of my invention shown in Fig. 5. there is provided both the pairs of ears and the teeth, and the fastoning possesses double strength and reliability on this account. Attention is directe to the fact that neither type of my fastening includes anything which passes through the body of the handle so that it would weaken the same. there is nothing which even enters or emited to the manner in which a hammer head of this character is made, but obviously the at least the outer end of the driving face D will be tempered to give them suiiicient hardness. The size and exact shape of parts is immaterial.

What is claimed as new is hammer head comprising a driving portion, a claw portion and a handle receiving boss therebetween, said boss being split in and a series of teeth at the inner periphery alinement with the claw, forming flanges of the outer end of the handle-receiving spaced from each other, cars extending ontopening in said boss and bendable inwardly weirdly at the egpoe'mg, edges of seidlfia/pges, tp'penetrate a handle en ned in said boss.

5 a screw passing through 'a smooth bore in In testimony whereof a '1; my signature. one ear and threaded into the other ear, CHARLES M. ERICKSON.
